I am trying to convert an Excel document into PDF in a ASP.Net Web application using Pdftron (Pdfnet) library. Following is my code for the above purpose.

    pdf.PDF.PDFDoc newSalaryFitmentPdf = new pdf.PDF.PDFDoc();
    pdftron.PDF.Convert.ToPdf(newSalaryFitmentPdf, newSalaryFitmentExcel.FullName);
salaryFitment = newSalaryFitmentPdf.Save(pdf.SDF.SDFDoc.SaveOptions.e_linearized);

But I am getting the following exception when the program is trying to execute the second line.

Exception: 
     Message: An error occurred while converting the file.
Detailed error:
    Error creating a new Excel application instance.
Code: PDFTRON_UNKNOWN (-2147024891)
      File: "Excel.cpp":51
    Log:
      Start check system account.
      Session ID is: 0.
      Failed to create Desktop folder in SystemProfile. boost::filesystem::create_directory: Access is denied: "C:\Windows\system32\config\systemprofile\Desktop"
      Failed to create Desktop folder in SystemProfile. boost::filesystem::create_directory: Access is denied: "C:\Windows\SysWOW64\config\systemprofile\Desktop"
      Done checking system account.
      Creating an Excel application instance.

     Conditional expression: false
     Version    : 6.7.1.61823N
     Filename   : Convert.cpp
     Function   : trn::PDF::Convert::ToPdf
     Linenumber : 1692

Any help would be highly appreciated.

    Seems you either do not have rights or you should run the app pool with user profile enabled which will allow for the use of a desktop folder. – Igor Aug 31 '17 at 15:32

You must set your application to have read/write access to these directories. Please see this article for further information.
